Specification of Letters Patent.

Patented June 29, 1909.

Application filed March 25, 1908, Serial No, 428,156. Renewed April 12,1909. Serial No. 489,525.

' To all whom it may concern:

Be it known that I, ETIIAN I. Donns, a citizen of the United States,residing in Central Valley, in the county of Orange and State of NewYork, have invented a new and useful Improvement in Brake Beams, ofwhich the following is a specification.

My invention relates to improvements in brake beams, and moreparticularly to brake beam fulcrums.

The object of my invention is to provide a brake lever fulcrum of asimple, eflicient and durable construction, capable of being cheaplymanufactured and readily and securely applied to the brake beam, and themembers or parts of which are adapted to be cut from metal plateswithout waste and readily forged or stamped into shape.

My invention consists in the means I employ to practically accomplishthis object or result, as herein shown and described and moreparticularly set forth in the claims.

In the accompanying drawing, forming a part of this specification,Figure 1 is a plan view of a brake beam embodying my invention; Fig. 2is a section on line 22 of Fig. 1 Fig. 3 is a front elevation; Fig. 4 isa section on line 44 of Fig. 1; Fig. 5 is a diagrammatic view showingthe form of the fulcrum members in the flat, and illustrating how theymay be cut from a metal plate without waste; and Fig. 6 illustrates amodification.

Inthe drawingArepresents the brake beam of 2. rolled steel I-beam shape,B B are my improved forged orstamped plate steel fulcrum members,each having a pair of right angle flanges b 7) adapted to fit betweenthe flanges a a of the brake beam A, and engage at their inner edges 6the web a Each of the fulcrum members B is further provided with anintegral twisted shank or tongue 6 having a hole 6 to receive the pivotpin of the brake lever. The shank or tongue b is twisted at an angle ofabout 45, so that the brake lever, which is between the shanks b b ofthe two fulcrum members B B may stand at an angle of about 45 or suchother angle as may be required to the brake beam. The two fulcrummembers B B are secured to the brake beam by a rivet or other clampingdevice C.

D D are filler blocks or thimbles, which may be inserted between theflanges b t of the fulcrum members B.

Each of the twisted shanks b is furnished with a bend b which snuglyhugs and embraces the outer face a of the adjacent brake beam flange a.The bends I) in the shanks of the plate steel fulcrum members B, inconflanges 5 serve to snugly anchor the fulcrum members to the brakebeam.

In the modification illustrated in Fig. 6 the blocks or thimbles D areenlarged to snugly of the fulcrum plate B.

I claim:

1. A brake beam fulcrum, comprising a pair of plate steel fulcrummembers fitting on opposite sides of the brake beam, each furnished withbent flanges at their side edges adapted to fit between the flanges ofthe brake beam and engage the web thereof, and a twisted shank having a11010 to receive the pivot pin of the brake lever, substantially asspecified.

2. The combination with a brake beam, of a fulcrum for the brake lever,comprising a pair of fulcrum plates, one fitting on each side of thebrake beam, and each having at its side edges flanges bent at an an lethereto fitting between the flanges of the brake beam, and a projectingbent shank portion to receive the brake lever, substantially asspecified.

3. The combination with a brake beam, of a fulcrum for the brake lever,comprising a pair of fulcrum plates, one fitting on each side of thebrake beam, and each having at its side edges flanges bent at an anglethere to fitting between the flanges of the brake beam, a projectingshank portion to receive the brake lever, and a rivet extending throughsaid fulcrum plates and the brake beam, substantially as specified.

4. The combination with a brake beam, of a fulcrum for the brake lever,comprising a pair of fulcrum plates, one fitting on each side of thebrake beam, and each havin at its side edges flanges bent at an angle tiereto fitting between the flanges of the brake beam, a projecting shankportion to receive the brake lever, a rivet extendin through saidfulcrum lates and the brake beam, and filler bloc frs, substantially asspecified.

5. The combination with a brake beam, of a fulcrum for the brake lever,comprising a pair of fulcrum plates, one fittin on each side of thebrake beam, and each liaving at its side edges flanges bent at an anglethereto nection with the bent side wings or angle fill the spacesbetween the bent side wings b fitting between the flanges of the brakebeam, and a projecting twisted shank portion to receive the brake lever.

6. A brake beam fulcrum, comprising a pair of metal plates having bentside wings adapted to fit between the flanges of the brake beam andengage the web thereof, said plates also having bent and twisted shanksembracing the adjacent flange of the brake beam and adapted to receivethe brake lever, substantially as specified.

'7. A brake beam fulcrum, comprising a pair of metal plates having bentside wings adapted to fit between the flanges of the brake beam andengage the web thereof, said plates also having bent and twisted shanksembracing the adjacent flange of the brake beam and adapted to receivethe brake lever, in combination with a brake beam and a connecting pinor rivet extending through said fulcrum lates and brake beam,substantially as speci led.

8. A brake beam fulcrum, comprising a air of metal plates having bentside wings ada ted to fit between the flanges 0f the bra e beam andengage the web thereof, said plates also having bent and twisted shanksembracing the adjacent flange of the brake beam and adapted to receivethe brake lever, in combination with a brake beam and a connecting pinor rivet extending through said fulcrum plates and brake beam, and apair of filler blocks or thimbles fitting between said bent side wingsof said fulcrum plates, substantially as specified.
